TT MBC RAINY DAY INSTALLATION
Not even considering the ability to incrementally increase boost, but more for the fact that it synchronizes the independent turbos.
I used a Hallman Pro RX primarily for it's design and light spring which allows fine tuning of boost adjustment.
The turbos spool up faster and by using the boost/control signal from the rear turbo only to open the wastegates gives identical performance to both turbos.
You must first install a boost gauge.
After installation of the MBC adjusted fully counter clockwise ( no increase over wastegate adjuster arm setting), I confirmed via a road test my set 7psi +/- mechanical setting.
What I noticed is that the boost is held at this level without dropping due to the inaccurate mechanical settings.
Haven't been able to road test a half turn increase as it started to rain.
Trying to get dyno time and 1/4 results in the next week or two.
